Abstract

Preparation of unsaturated methyl ketones(I), from an unsaturated alcohol(II) and alkyl acetoacetate(III) in the presence of an organo-aluminum catalyst(IV) comprises: (a) supplying (II) and (IV) to a reactor with a distillation column, (b) making temperature to be 170-250 degrees C under elevated pressure, (c) dosing the mixture with (III) and (d) maintaining a constant (III) content of 0.1-10 wt.% during the reaction. Preparation of unsaturated ketones of formula (I) involves reaction of an unsaturated alcohol of formula (II) with an alkyl acetoacetate of formula (III), in presence of 0.1-5 mol. % (based on (II)) of an organo-aluminum compound catalyst (IV), with elimination and distillative separation of the alcohol R3OH formed in the reaction, in a reactor system provided with a distillation column. Reaction is carried out by: (a) supplying (I (which boils at less than 140 degrees C), without a solvent, and (IV) to the reaction vessel, (b) adjusting the temperature to a value as constant as possible in the range 170-250 degrees C under elevated pressure, (c) dosing the mixture with (III) and (d) maintaining a (III) content as constant as possible in the range 0.1-10 wt. % during the reaction. Dotted line = optional bond; R1 = Me or Et; R2, R3 = 1-4C alkyl.
